Step-by-step explanation:
<h3>Simplifying radicals</h3>
Step1: Prime fatorize and reduce to simplest form
Step2: Combine like radicals


(10,5)
Explanation:
By replacing the value of x with the x co-ordinate of the point above, we get that;
y=10+5
y=15
This does not tally with (10,5)
Answer:
Given : BRDG is a kite that is inscribed in a circle,
With BR = RD and BG = DG
To prove : RG is a diameter
Proof:
Since, RG is the major diagonal of the kite BRDG,
By the property of kite,
∠ RBG = ∠ RDG
Also, BRDG is a cyclic quadrilateral,
Therefore, By the property of cyclic quadrilateral,
∠ RBG + ∠ RDG = 180°
⇒ ∠ RBG + ∠ RBG = 180°
⇒ 2∠ RBG = 180°
⇒ ∠ RBG = 90°
⇒ ∠ RDG = 90°
Since, Angle subtended by a diameter or semicircle on any point of circle is right angle.
⇒ RG is the diameter of the circle.
Hence, proved.
Accuracy is the degree of closeness of measurements to the actual or accepted value
